Write the equation of a line that passes through the point (6,8) and is parallel to y = 2x + 1.
Answer:
y = 2x - 4
General Formulas and Concepts:
Alg I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptParallel Lines have the same slope but different y-intercepts.
Step-by-step explanation:
Step 1: Define
y = 2x + 1
Step 2: Break function
Slope m = 2
y-intercept = 1
Step 3: Set up parallel line
y = 2x + b
8 = 2(6) + b
8 = 12 + b
b = -4
y = 2x - 4
Answer:
y = 2x - 4
Step-by-step explanation:
y - y1 = m(x - x1)
y - 8 = 2(x - 6)
y - 8 = 2x - 12
+ 12 + 12
y + 4 = 2x
- 4 - 4
y = 2x - 4 ------- formula for slope-intercept form: y = mx + b

Which inequality is represented by this graph?
5+
(0,1)
(3,0)
A. ys-3x+1
B. y>-*x+1
C. 72-3x+1
D. y< -1x+1
The inequality is represented by the given graph is y ≤ -x/3+1.
The correct option is B.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.
We have,
A graph of an inequality, passing by (0, 1) and (3, 0).
A and D are eliminated since the line is solid.
C is disregarded because the line is shaded below as well.
Then, the inequality will be y ≤ -x/3+1
Hence, the inequality is represented by the given graph is y ≤ -x/3+1.

The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of Earth from the Sun is 1.5 ⋅ 108 kilometers. About how many more kilometers is the distance of Earth from the Sun than the distance of Mercury from the Sun?
4.3 ⋅ 107 kilometers
9.2 ⋅ 107 kilometers
9.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers
Answer:
If you take a look at, 1.5 kilometers you can see that Mercury from the Sun is 5.8, it is also asking how many more kilometers is the distance of earth, so if you look at 5.1 and D which is 5.7 you would add those last digits together and get 5.8 so therefore your answer could possibly be D) 5.7 ⋅ 109 kilometers

On the caculator there are two buttons you need to press. 2nd and then x2. Once you press those add in 20.
You get 4.47 ROUND THAT to 4.5
12(2)+4.5(2)=C(2)
12×12=144 4.5×4.5=20.25
144+20.25=164.25
164.25=C(2)
On the caculator press 2nd and then x2
12.81=12.8
C=12.8

Your friend decided to join a bmx course so he can race with his friends. The
courses charges $7 per race after the membership fee. Your friend has raced 28
times and paid a total of $210, including the membership fee. What is the
membership fee? How much would he pay if he races 39 times? *
Answer:
He would pay $287 if he races 39 times
Thus, the membership fee is $14.
Step-by-step explanation:
Linear Modeling
The situation described in the problem can be modeled as the equation of a line which has the form:
[tex]y=ax+b[/tex]
Where y is the cost of the course, x is the number of races, a is the cost per race, and b is the membership fee.
We know the course charges $7 per race, so a=7. Since your friend has raced x=28 times and paid y=210, we can find the value of b:
[tex]210=7(28)+b[/tex]
Operating:
[tex]210=196+b[/tex]
b=14
Thus, the membership fee is $14.
The linear model is now:
[tex]y=7x+14[/tex]
If he races x=39 times, your friend would pay:
[tex]y=7(39)+14=287[/tex]
y=287
He would pay $287 if he races 39 times

Greg’s Kitchen sells pans for $22 and pots for $9. Greg’s Kitchen also offers two coupons: 2POTSFOR1 (2 pots for the price of 1) and WELCOME25 (25% off your entire order). A customer would like to buy two pots and one pan. If the customer uses the best coupon, what will their total be?
Answer: the best coupon for this case is WELCOME25, and the cost will be $30.
Step-by-step explanation:
We know that:
Price for pans = $22
Price for pots = $9.
If the customer buys two pots and one pan, he would pay::
C = 1*$22 + 2*$9 = $40.
If the customer uses the coupon 2POTSFOR1
Then he will pay only one of the pots, and the total cost will be:
C = 1*$22 + 1*9 = $31.
If the customer uses the WELCOME25 coupon, then the cost will be a 75% of the original cost.
if 100% = $40
then:
75% = C
Where
We can take the quotient of these equations and get:
(C/$40) = (75%/100%)
C = (75%/100%)*$40
C = 0.75*$40 = $30
Then the best coupon for this case is WELCOME25, and the cost will be $30.
Period 5 is gearing up for a class ice cream party. Meghan plans to arrange the party and understands that ice cream cones cost $1.10 and sundaes cost $2.35. On the day of the party the receipt shows a total of 172 cones and sundaes were $294.20. How many cones were sold?
Answer: 88 cones.
Step-by-step explanation:
We know that:
price of a cone = $1.10
price of a sundae = $2.35
A total of 172 cones and sundaes were sold for $294.20
Then we can define two variables:
C = number of cones sold
S = number of sundaes sold.
C + S = 172 (the total number of sundaes and cones sold is 172)
C*$1.10 + S*$2.35 = $294.20 (that is how much the won).
Then we have the system of equations:
C + S = 172
C*$1.10 + S*$2.35 = $294.20
And we want to find how many cones were sold.
To solve this, we first need to isolate the other variable, S, in one of the equations, i will isolate S in the first equation:
S = 172 - C
Now, let's replace this in the second equation:
C*$1.10 + (172 - C)*$2.35 = $294.20
Now we can solve this for C, and find the number of cones that were sold.
C*$1.10 + $404.20 - C*$2.35 = $294.20
C*($1.10 - $2.35) = $294.20 - $404.20
-C*1.25 = -110
C = 110/1.25 = 88
88 cones were sold.
